Filed sept. 5, 1944 Hvmt Patented Oct. 28, 194'? UNITED STATES PATENT OFFICE PROJECTILE Leo E. Beavers, Lone Oak, Tex.y Application September 5, 1944, Serial No. 552,761 1 claim. (01. 1oz-56) (Granted under the act of March 3, 18583, as amended April 30, 1928; 370 O. G. 757) `which is automatically self-arming upon being red from a gun.

-A further object of my invention is to provide "q, a projectile of this character in which chamber pressure, caused by firing a gun, operates the arming system.

l A- still further object of my invention iS to Drovide a projectile of this character in which the mechanism will not become displaced after being armed, during the flight of the projectile.

i A still further object of my invention is to pro vide a projectile of this character which is extremely sensitive, when armed, and one which will explode when only very little resistance is encountered, such as the thin sheeting of airplane wings, etc.

A still further object of my invention is to provide a projectile of this character which is simple in construction, which may readily and quickly be assembled and one which will not become armed until the gun containing the proclaim, reference is now made to the accompanying drawings forming a part of this application, in which:

F'igure 1 is a vertical, longitudinal section View of my improved projectile, illustrating the normal position of the mechanism before arming;

Figure 2 is a view similar to the View of Fig. 1, illustrating the projectile in armed position;

Figure 3 is a side elevational View, partly in section, illustrating the detonator shell;

Figure 4 is a side elevational View illustrating the primer charge holder; and

Figure 5 is a top plan view of the primer charge holder shown in Fig. 4r

Referring now to the drawings in which similar reference characters represent similar parts, the

numeral 2 represents a hollow, cylindrical jacket forming the casing of the projectile of metal, alloy, or the like or any other suitable composition or material known in the art, recessed near the base to form an annular shoulder 4. The nose of the jacket 2 is flat, as indicated at 6 with a longitudinal, circular opening 8 extending therethrough. A conical ller I0 of lead or other suitable metal or material is positioned with the hollow nose portion of the jacket, may be held securely in place by crimping the jacket, as shown at l2 or which may be otherwise suitably secured in such position. Filler l 0 is provided with a oentral, circular longitudinal opening I4 adapted to receive a striker member i6, the front end I8 of which may be smaller in diameter than the body of member I 6, and which is adapted to contact the object or target on impact. 'I'he opposite end 29, of striker member i6 is riveted through an opening in charge case end cap 22, which end cap is provided with a circular angularly disposed recess adapted to receive and frictionally hold in position the angularly crimped rim 24 of detonator shell 26. Detonator shell 26 is provided with'oppositely disposed recesses 28 and 3E! adapted to receive and frictionally hold in position the legs 32 and 34 of the primer charge holder 36, which holder is provided with a circular recess 38 having a small circular opening 40 through the central portion of the base of the holder. lThe recess 38 is adapted to hold a primer charge 42, as shown in Fig. 1, while the detonator shell 26 is adapted to hold a suitable detonating charge 44 also shown in Fig. 1. A circular, hollow charge carrying case 46 is provided with an annular base 48 extending outwardly from the outside surface of case 46 to form an annular rim 50 adapted to Contact the annular shoulder 4 of jacket 2 and to limit the forward movement of case 46 and connected Parts. Case 46 is crimped to form an annular shoulder 52 which serves to prevent rearward movement of charge case end cap 22, while the front edge of case 46 is turned inwardly or crimped, as shown by numeral 54 over the charge case end cap 22, thus firmly holding end cap 22 in fixed position. The base portion of filler l0 is provided with an annular, peripheral recess 56 adapted to receive the crimped portion 54 of case 46. The charge carrying case 46 is adapted to contain any suitable, desired explosive, not shown. The base edge of jacket 2 is crimped slightly, as shown at 58, after the charge carrying case 46 has been inserted in the jacket 2 to prevent the case from sliding or falling out of the jacket, while the diameter of the recessed portion of the jacket gradually narrows from the base to shoulder 4 of the jacket, to insure a wedging elect of the base 48 against the recessed portion of jacket 2, and a secure frictional engagement therewith.

In assembling, the ller I is inserted in the nose of the jacket 2 and crimped in position, as shown at4 l2. A suitable explosive is placed within the charge carrying case 46, enough room being left in the case for the detonating shell 26 which is adapted to contain a suitable detonat-y ing charge 44'. The primer charge holder 36 is inserted in placein the detonator shell anda suitable primer `42 is inserted in the holder. Striker member I6 is riveted to the central recessed portionof the charge case end cap 22 and the detonator shell is forced into lthis recessed portion. The charge case endcapis then inserted in the front end of the charge carrying case 46 abutting the annular crimped shoulder- 52, and the front edge of the charge carrying case is crimped or turned in as shown in 54 thereby whereby the base 48 will mold itself to the contour of the recess. When the forward movement is completed, the front end I8 of striker member I6 protrudes forwardly of the projectile and is thereby in position to contact an object or target on impact therewith, such impact forcing the striker member rearwardly against the primer, thus starting the chainiof explosion.

While Ivhave illustrated and described the invention in some detail, it is to be understood that the invention is not to be limited to such details, but only by the spirit of the invention and the holding in Xed assembled-forni the charge car'- Y rying case, the case end cap,Iv detonator shell, primer holder, and striker member. This entire assembly is then inserted in the jacket through the base thereof, the striker member extending through the opening l4xof'f1ller I'U,.and into but notl through opening' 8 ofnose 6 of the jacket. Duev to the gradual decreasingv of the diameter of the recess in thebase of jacket 2, the base 48 of case 46 will eifect a tightft and prevent further forward movementfrom-the position shownv i-n Fig, 1 until such time las considerable force is applied to the base. :When'the' assembled mechanisrn reaches the position shown inv Fig., 1, the base of the jacket is' crimped as shown` at. 58` to prevent the assembled mechanismjfrom sliding or falling from the projectile.

When the projectile isv fired from ai gung. the chamber pressure' created by such firing forces the'. entire mechanismv forward tothe position shown in Fig. 2,` further forward movementbeing prevented by the filler I0, and. bycontaot of rim 50 of basez48 with shoulder 4'of jacket 2'.4 In this forward Irlovement,l base 48- will expand the recessed: portion. of jacket 2fslight1y, thus insuring a tight, frictional'. engagement of these twoparts,
